The purpose of the survey is satisfy condition 13 – Planning Application No: 162950 in accordance with the provisions of the National Planning Policy Framework, the Noise Policy Statement for England (NPSE) and the World Health Organisation Guidelines for Community Noise 1999 (WHO) and Wokingham Borough Council Local Plan. This report presents the results of background noise levels and outlines any necessary mitigation measures The technical content of this assessment has been provided by a Tech member of the Institute of Acoustics. The Institute of Acoustics is the UK’s professional body for those working in acoustics, noise and vibration 2.0 NOISE CRITERIA 2.1 NATIONAL PLANNING POLICY FRAMEWORK (NPPF) The Department for Communities and Local Government introduced the National Planning Policy Framework (NPPF) in March 2012. The latest revision of the NPPF is dated July 2018. The NPPF sets out the Government’s planning policies for England and how these are expected to be applied. It provides a framework where local Councils can produce their own local and neighbourhood plans which reflect the needs of their communities. In conserving and enhancing the natural environment, the planning system should prevent both new and existing development from contributing to, or being put at, unacceptable risk from environmental factors including noise. Planning policies and decisions should aim to avoid noise giving rise to significant adverse impacts on health and quality of life as a result of new development. Conditions may be used to mitigate and reduce noise to a minimum so that adverse impacts on health and quality of life are minimised. It must be recognised that development will often create some noise and existing businesses wanting to develop in continuance of their business should not have unreasonable restrictions put on them. Reference is made within NPPF to the Noise Policy Statement for England (NPSE) as published by DEFRA in March 2015 T: +44(0)202 101 9669. F: +44(0)1252 337266. E: [email protected] Deane Austin Ltd Company No: 0249971 2.2 NOISE POLICY STATEMENT FOR ENGLAND (NPSE) The long-term vision of the NPSE is stated within the documents scope, to ‘promote good health and a good quality of life through the effective management of noise within the context of Government Page | 4 policy on sustainable development’. The policy aims are stated to: • avoid significant adverse impacts on health and quality of life; • mitigate and minimise adverse impacts on health and quality of life; and • where possible, contribute to the improvement of health and quality of life. The application of NPSE should mean that noise is properly taken into account at the appropriate time (for example in planning applications or appeals) where it must be considered alongside other relevant issues. The guiding principles of Government policy on sustainable development should be used to assist in the implementation of the NPSE. The NPSE should apply to all types of noise apart from occupational noise in the workplace. The types of noises defined in the NPSE includes: • Environmental noise from transportation sources; • Neighbourhood noise which includes noise arising from within the community; industrial premises, trade and business premises, construction sites and noise in the street The Noise Policy Statement England (NPSE) outlines observed effect levels relating to the above, as follows: • NOEL – No Observed Effect Level o This is the level below which no effect can be detected. In simple terms, below this level, there is no detectable effect on health and quality of life due to the noise. • LOAEL – Lowest Observed Adverse Effect Level o This is the level above which adverse effects on health and quality of life can be detected. • SOAEL – Significant Observed Adverse Effect Level o This is the level above which significant adverse effects on health and quality of life occur. As stated in The Noise Policy Statement England (NPSE), it is not currently possible to have a single objective based measure that defines SOAEL that is applicable to all sources of noise in all situations. Specific noise levels are not stated within the guidance for this reason, and allow flexibility in the policy until further guidance is available. 2.3 ProPG: PLANNING AND NOISE As outlined above, the National Planning Policy Framework encourages improved standards of design, although it provides no specific noise levels which should be achieved on site for varying standards of acoustic acceptability, or a prescriptive method for the assessment of noise. ProPG: Planning and Noise was published in May 2017 in order to encourage better acoustic design for new residential schemes in order to protect future residents from the harmful effects of noise. This guidance can be seen as the missing link between the current NPPF and its predecessor, PPG24 (Planning Policy Guidance 24: Planning and Noise), which provided a prescriptive method for assessing sites for residential development, but without the nuance of ‘good acoustic design’ as outlined in ProPG. ProPG allows the assessor to take a holistic approach to consider the site’s suitability, taking into consideration numerous design factors which previously may not have been considered alongside the noise level measured on site, for example the orientation of the building in T: +44(0)202 101 9669. F: +44(0)1252 337266. E: [email protected] Deane Austin Ltd Company No: 0249971 relation to the main source of noise incident upon it. It should be noted this document is not an official government code of practice, and neither replaces nor provides an authoritative interpretation of the law or government policy, and therefore should be seen as a good practice document only. 2.4 ACOUSTICS VENTILATION AND OVERHEATING Page | 5 The AVO Guide includes: an explanation of ventilation requirements under the building regulations and as described in Approved Document F, along with typical ventilation strategies and associated noise considerations; an explanation of the overheating assessment methodology described in CIBSE TM59; potential acoustic criteria and guidance relating to different ventilation and overheating conditions, for both environmental noise ingress and building services noise; and a worked example of the application of the AVO Guide including indicative design solutions. The AVO Guide is intended for the consideration of new residential development that will be exposed predominantly to airborne sound from
